Menene banbanci tsakanin PCB da PCBA?

PCB: Buga kwamiti na da'irar jirgi ne ba tare da kayan aikin lantarki ba. Ya ƙunshi an haɗa da substrate, da'irar kumfa da kuma kushin. An kafa da'irar a substrate ta hanyar etching etching da sauran matakai, kamar saitin abin da aka gyara, kawai ana samar da saƙo na ainihi, yi ".

Maɓallin PCBA: buga da'irar jirgin gida shine samfurin da aka gama bayan shigar da kayan haɗin lantarki daban-daban (kamar kwakwalwa, da sauransu, da kuma bayan jerin matakai kamar waldi. Ya yi daidai da shirya 'yan wasan kwaikwayo (kayan lantarki) a kan mataki, da sake karanta (debuging), kuma zai iya yin aikin samfuran lantarki).
